The lower end of this cavity is closed to prevent the escape of the cooling material with which it is filled.

The agitator c is for the purpose of occasionally stirring the ice and water beneath the cooling-surface of the conductor a in order that its temperature may be maintained nearly as low as the water and ice beneath.

d represents the rectangular receptacle for is being operated is placed over the same, thus forming an inclosed space through which the milk or cream flows, the bottom surface frost is formed by the action of the salt on the ice contained therein.
